【Abstract】 The apomixis of plant is a kind of reproduction that seeds are produced without fertilization in ovules. It consists of diplospory, apospory and adventitious embryony. It has broad prospects of application in stabilizing hybrid vigour, avoiding producing seeds every year and reducing the cost of hybrid seeds. There are many ways to distinguish the apomixis of plant and also many ways to create the apomixis of plant artificially.更多还原
